Hi Pliablepixels,
Your are my hero!....Paths are not as exact as mines. My paths are:
source: plugins\com.phonegap.plugins.PushPlugin\src\android\com\plugin\gcm
targer: platforms\android\src\com\plugin\gcm
Now, i modified target and changes are compiled and included on the apk.
Thanks, thanks, thanks.
Regards
